Battery Terminal Connector Replacement Made Easy

by Don Elliott on July 27, 2012

Problems with a car battery can be frustrating, expensive and inconvenient. Replacing a battery is not a difficult job for anyone with a little mechanical ability. Any automotive service shop, big box automotive department, or Batteries Plus outlet will test your battery for little or no cost on the hope that they will be able to sell you a battery.

What if it’s not the battery causing the problem? A visual inspection might indicate that the connector at the end of the battery cable where it is attached to the battery has corroded or broken preventing the flow of electric power. It would seem to be a simple job to replace the connector to the batteries positive (+) or negative (-) terminals.

There are two problems with replacing the terminal connectors yourself. First, it is necessary to cut the battery cable far enough from the existing connector to find good clean wire. Replacing the connector at the end of the cable requires a crimping tool, readily available in most auto technician’s toolbox, but not usually available for the do-it-yourself home mechanic. Second, there may not be enough cable to reconnect to the battery terminal after a few inches are cut off.

Car repair shops know about Quick Cable Ends. Quick Cable Ends, available in most auto parts stores, add six inches to the battery cable and provide for replacement with a few common tools. To replace a corroded or broken battery cable connector, tools required include a cable cutter, a cable stripper or box knife, a ½” wrench and a Vice Grip tool. Also required is whatever sized wrench needed to remove the connector from the battery terminal.

Quick Cable Ends are available in both top terminal and side terminal configurations typical on most car and light duty truck batteries. The Quick Cable Company manufactures energy storage products for all types of vehicles.

To replace the corroded or broken battery cable connector, remove the battery cable connector from the battery terminal. Cut the cable far enough back from the connector to be in good wire. Strip ¾” of insulation from the cable being careful not to cut any of the wires in the battery cable. Slide the Quick Cable End over the stripped battery cable. Hold the metal flange with the Vice Grip and use the ½” wrench to tighten the clamp. Snap on the protective boot and you are done!

Before reconnecting the repaired battery cable to the battery terminal, apply some corrosion protection to add life to both the battery and the new battery cable connector.
